JOURNAL-Box COVER.

I To all whom it'm ay concern.

Be it known that I, LAUMAN A. RUlfNING, a citizen of the United States, residlng at Two- Harbors, in the county of Lake and State of Minnesota, have invented certain new and useful Improvements in J ournal- Box Covers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in connection with journal boxes and has special referenc to a simple cover. or closure for the upper open end of the dust guard opening formed in the. inner end of the ordinary rail road car journal box.

WhileI have shown the invention as applied to such a journal box, it is to be under-' stood that the same is not restricted to this specific adaptation and is susceptible of various changes in construction and modifications within the scope of the appended claims without departing from the spirit thereof. j

The primary object is to provide means in conjunction with the ordinary dust guard for journal boxes which insures their proper functioning by preventing dust or grit from entering the upper end of the opening which contains the dust guard.

Other objects and advantages of the intion thereof. In the accompanying drawings fornnng part of this application and in which like reference characters indicate like parts:

Figure 1 is a central longitudinal vertical sectional view through a. journal box equipped with one of my improved dust covers, and

Fig. 2 is a top plan view of same.

1 represents the journal box into which the end 2 of the car axle 3 extends andi Y which it is journaled.

The opening l in the inner end of the box through which the axle extends is of necessity considerably larger in diameter than that portion of the axle therein, and tociprocably mounted within a suitable channel or opening 6 formed adjacent the inner end of the box.

The box being substantially rectangular Specificationlof Letters Patent.

the free. end as indicated at 12. is turneddown about its outer edges form- '90 Patent ed Dec. 17, 191s.

Application filed July 1,' l918. Serial No. 242,773.

in cross section and the dust guard loosely fitted within the opening 6, permit of the g necessary movement of the latter, and the walls'surrounding the upper open end of the dust guard opening usually extend slightly 6.0

above the top of the journal box. This results in the coaming 7 about the opening of the dust-guard being of elongated. rectangular form as shown in dotted lines Fig. 2.

To form a suitablecover for this opening is the purpose of my present'invention and it accomplished in the following manner: I, A thin :piece of strongsheet metal indicated at 8 is made to fit on top of the re inforcement 9 on the upper face of the box and lies between it and-the arch bars indicated at 10. As is well known, the arch bars are held on the box by suitable strong bolts 11, one upon each side of the box, and the cover 8 is provided with suitable holes therein-through which the bolts 11 extend, thus holding the cover at all times rigidly in place when the arch bars and box are assembled. Y I T For clearness of illustration,- I have shown the cover as being composed ofconsiderably thicker material than is commonly used as the thinsheet metal which I employ does not "operate to destroy the necessary tight fit of the arch bars upon the journal box. vention will appear in the further descr1p I The outer free end of the cover is bentupwardly and thenagain parallel with the body portion forming a sort of cap upon This cap ing a flange 13 thereabout and which flange,

due to the cover being narrower at the free end than at its fixed end and being stepped as at 14, curves gracefully as at 15 form ing a partial protection to the ends of the through space 16 intermediate of the 00aming .7 and the reinforcement 9.

In thismanner a complete and close fitting cover or closure is provided for the open end of the dust guard opening and is held firmly in place at all times when the arch bars are bolted to the box. I v As is well known, there are different forms of side. frame and journal box connections, and I have shown in dotted lines as at 17,

Fig. 1, what is known as the Battendorf side frame. a

With this o a like form of frame, the fastening 'end of the cover plate 8 may be turned up at right angles as shown at 1$ and rigidly secured to the side frame with suitable small bolts 19, which in all. respects will answer equally as Well as the other form of securing means.

Having thus described my invention, what I desire to secure by Letters Patent and consider new is 1. The combination with a journal box having a dust guard opening therein 'and a coamin'g about the opening, of a cover for the openin flat upon the upper surface of the box and rigidly fixed thereto and an upwardly stepped portion having depending flanges about the edges thereof surrounding the coaming.

2. The combination with a car journal having a portion thereof lying box having arch bars thereupon and a dust guard opening therein, of a cover held intermediate of the box and arch bars and extending over the dust guard and acting as J. G. JELLE, ANDREW EILERTSON.
